foot crank. The lifting capacity is 1000 kg (2206 lb).

ATTENTION: Only authorized personnel should operate the lift cart. Keep hands
and feet away from the lifting mechanism. Do not stand under the lift tray
when in use. Store the lift cart with the tray fully lowered.

Turn the Pressure Release Knob clockwise
until tight.
3.
Raise the lift tray using the Hand Crank or the
Foot Crank.

the drive. Use the Hand Crank for final
precise positioning.
